Silicone is generally a liquid or a flexible, rubberlike plastic, and has a number of useful properties, such as low toxicity and high heat resistance. It also provides good electrical insulation.

Is silicon a metal or gas?

Is silicon a metal? No, silicon is classified as a metalloid because some of its properties resemble the properties of metals and some of its properties resemble those of nonmetals.

Why is silicon the best semiconductor?

The pure form of silicon has an atomic structure that makes it highly effective as a semiconductor. This means it has the conductive properties of metal as well as being an insulator, so silicon can conduct and block electricity. This ability makes silicon ideal as a switching mechanism.

Silicon has historically been used to make transistors because it is a semiconductor, which is a material that is more conductive than an insulator like rubber but less conductive than a metal like steel, according to the Encyclopedia Britannica.

Why silicon is not used in LED?

Since Silicon is an Indirect Band Gap semiconductor so electron cannot fall directly to the valence band but must undergo a momentum change as well as a change in energy. So, energy is released as heat along with the light. Hence, silicon is not suitable for the fabrication of LEDs.
